Question

in triangle ABC if a=50 b=60 then find the value of c=?
​

Answer 1

Answer:

70

Step-by-step explanation:

we know that sum of all sides is 180

a+b+c=180

50+60+c=180

110+c=180

c=180-110

c=70

hope it helps.....

Answer 2

Sum of angles of triangle is 180°

$\: \: \: \: \: \: \: \: ∠ A+∠B+∠C = 180$

$\: \: \: \: \: \: \: 50 + 60 +∠C = 180$

$\: \: \: \: \: \: \: \: \: \: \: \: \: ∠C = 180 - 110$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed {∠C = 70}$
